Ammonia can be obtained according to reaction (b) or (c). Which of the following is correct regardin — Thermodynamics and Thermochemistry Chemistry Question

💡 Solution & Explanation

Reaction (b) is highly endothermic (ΔH = +241.35 kcal per 2 moles $NH_3$) compared to reaction (c) (ΔH = +34.18 kcal per 2 moles $NH_3$). Thus, for the same mass of ammonia produced, reaction (b) requires more heat energy.
